Honda Maintenance Minder

Dashboard Warning Lights Guide

Honda's clever Maintenance Minder system ditches old-school calendar and odometer-based check-up reminders. Instead, it lets you know exactly what it needs with easy-to-understand codes. This system assesses how you drive, the condition of the roads you use, and even the weather you travel through. All of these factors can affect the frequency of maintenance tasks. Use our easy guide to understand what each code means.

When your Honda needs a little TLC, it doesn’t just nudge you with a generic oil change light. Instead, it shows you how much life your engine oil has left in percentages right on your dashboard. Fresh oil starts at a cheerful 100%, but as you rack up miles, it counts down. When it reaches 15%, it's time for an oil change. Your car will display a maintenance minder light that is sometimes accompanied by a wrench icon along with letters and numbers – these are your keys to understanding exactly what kind of service your Honda needs.

Deciphering Your Maintenance Minder Messages

Now that we've gone through what each code and letter means, let's tie it all together with a quick example. If your Honda maintenance minder displays a wrench and the code "B4." This means it's time to get an oil change and filter replacement. Plus, you'll need to check if your spark plugs and timing belt are due for a replacement. If you see any codes on your maintenance minder, you should book an appointment with the service crew here at CMA’s Honda of Winchester.
